[0002] In the petrochemical industry, medium-frequency pipe bending machines are frequently used. When bending pipes, the medium-frequency pipe bending machine first locally heats the bending section of the pipe using a medium-frequency induction coil, then pushes the rear of the pipe through the bending die to achieve the bending purpose.

[0014] In one possible implementation, one end of the slide rail faces the bending device, and the end of the slide rail facing the bending device has a limiting member for contacting the side of the support seat to limit the sliding position of the support seat.

[0015] In one possible implementation, the walking mechanism includes:

[0016] Four mounting bases are respectively located at the four corners of the support base; each mounting base is rotatably equipped with a guide wheel;

[0017] Four lateral sliding structures are respectively connected to the corresponding mounting bases; each of the four corners of the support base is provided with a lateral sliding groove, and the lateral sliding structures are slidably disposed in the lateral sliding grooves.

[0018] Four limiting structures are provided, each corresponding to one of the lateral sliding structures, and are respectively set on the corresponding lateral sliding structures.

[0019] The transverse sliding structure has a first sliding position and a second sliding position. The transverse sliding groove is provided with a first limiting groove at both the first sliding position and the second sliding position. The limiting structure is used to insert and cooperate with the first limiting groove.

[0020] In one possible implementation, the transverse slide includes a first slide through the support base and a second slide disposed on the top of the support base and communicating with the first slide; the first slide and the second slide have the same length, and the width of the second slide is greater than the width of the first slide.

[0021] The lateral sliding structure includes a first sliding part that slides in conjunction with the first sliding groove, and a second sliding part that slides in conjunction with the second sliding groove; the two opposite sides of the second sliding part respectively contact the two side walls of the second sliding groove.

[0022] In one possible implementation, the lateral sliding structure has a second limiting groove for alignment with the first limiting groove; the limiting structure includes:

[0023] A limiting slider is slidably disposed in the second limiting groove; one end of the limiting slider is used to insert and cooperate with the first limiting groove to laterally limit the lateral sliding structure.

[0033] This invention provides a connecting pipe device for a medium-frequency push-bending pipe equipment. Compared with the prior art, before cutting the bend, a support base is placed directly below the bend, and the traveling mechanism is inserted into a first groove. With this arrangement, the traveling mechanism is suspended when the bottom of the support base contacts the ground. After cutting the bend, it falls onto a buffer component, which cushions the bend and reduces damage caused by impact. Because the traveling mechanism is suspended, there is no reaction force acting on it when the bend falls onto the support base, thus reducing damage to the traveling mechanism. Furthermore, with the traveling mechanism suspended, the bottom of the support base contacts the ground, increasing the contact area and improving its impact resistance. When the cut bend falls onto the support base and is stationary, the lifting mechanism lifts the support base upwards, which pushes the traveling mechanism out of the first groove. At this time, the traveling mechanism slides laterally, which allows the traveling mechanism to be misaligned with the first groove. During the movement of the traveling mechanism, it can prevent the traveling mechanism from falling into the first groove, thus facilitating the transportation of the cut bend.

[0045] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0046] Please refer to the following: Figures 1 to 10The present invention provides a connecting pipe device for a medium-frequency push-bending pipe equipment. The connecting pipe device includes a support base 1, at least two buffer components 2, a traveling mechanism 3, and a lifting mechanism 4. The bottom of the support base 1 is for contacting the ground 5. The top of the support base 1 has several preset buffer positions. Each buffer component 2 is disposed at a corresponding buffer position, and each buffer component 2 is located directly below the bend. The traveling mechanism 3 is disposed at the bottom of the support base 1 and has a degree of freedom for lateral sliding. The ground 5 has a first groove 51 for avoiding the traveling mechanism 3. The lifting end of the lifting mechanism 4 is for contacting the bottom of the support base 1 to lift the support base 1, thereby pushing the traveling mechanism 3 out of the first groove 51. The ground 5 has a second groove 52 for installing the lifting mechanism 4. When the traveling mechanism 3 separates from the first groove 51, the traveling mechanism 3 slides laterally to avoid the first groove 51. The depth of the first groove 51 is greater than the height of the traveling mechanism 3.

[0047] This invention provides a connecting pipe device for a medium-frequency push-bending pipe equipment. Compared with the prior art, before cutting the bend, a support base 1 is placed directly below the bend, and a traveling mechanism 3 is inserted into the first groove 51. With this arrangement, when the bottom of the support base 1 contacts the ground 5, the traveling mechanism 3 is suspended. After cutting the bend, it falls onto a buffer component 2, which cushions the bend and reduces damage caused by impact. Because the traveling mechanism 3 is suspended, there is no reaction force acting on it when the bend falls onto the support base 1, thus reducing damage to the traveling mechanism 3. Furthermore, when the traveling mechanism 3 is suspended, the bottom of the support base 1 contacts the ground 5, increasing the contact area between the support base 1 and the ground 5 and improving the impact resistance of the support base 1. When the cut bend falls onto the support base 1 and is stationary, the lifting mechanism 4 lifts the support base 1 upward, which pushes the traveling mechanism 3 out of the first groove 51. At this time, the traveling mechanism 3 slides laterally, which can make the traveling mechanism 3 misaligned with the first groove 51. During the movement of the traveling mechanism 3, it can prevent the traveling mechanism 3 from falling into the first groove 51, thus facilitating the transportation of the cut bend.

[0048] It should be noted that the connecting pipe device is located at the bend position of the pipe bending device 6. During normal pipe bending, the support base 1 does not need to be placed directly below the bend. Before cutting the bend, the support base 1 is placed directly below the bend, and the position of the buffer component 2 is adjusted to provide cushioning for the cut bend. The buffer component 2 can be a waste tire. Through the above arrangement, the cut bend can be well cushioned, thereby reducing the damage caused by impact after the bend falls.

[0049] For example, the support base 1 is provided with railings 7 on the two adjacent right-angled sides at the top. The railings 7 serve a protective function to ensure the safety of the operator. The operator can pull the railings 7 to slide the support base 1, thus facilitating the transportation of the cut pipe.

[0050] In some embodiments, such as Figures 1 to 10 As shown, the connecting device also includes a slide 53 for guiding the walking mechanism 3, the slide 53 being disposed on the ground 5; wherein, the slide 53 is offset from the first groove 51, and the position of the slide 53 corresponding to the first groove 51 has an opening 54 for the lateral sliding of the walking mechanism 3.

[0051] It should be noted that by setting a slide rail 53 on the ground 5, the walking mechanism 3 can be guided. After the walking mechanism 3 moves into position, it corresponds to the opening 54 on the slide rail 53. At this time, the support base 1 is lifted and supported by the lifting mechanism 4, and the operator can slide the walking mechanism 3 laterally so that the walking mechanism 3 is directly above the first groove 51. When it moves downward into position by the lifting mechanism 4, the walking mechanism 3 can be inserted into the first groove 51, and the bottom of the support base 1 contacts the ground 5. By setting an opening 54 on the slide rail 53, it is convenient for the walking mechanism 3 to slide laterally, so that the walking mechanism 3 can disengage from the slide rail 53 or move laterally into the slide rail 53.

[0052] In some embodiments, such as Figures 1 to 10 As shown, the traveling mechanism 3 includes guide wheels 31 located at the four corners of the bottom of the support base 1, which rotate in conjunction with the support base 1. The slide 53 consists of two parallel limiting plates 55, the sidewalls of which are respectively used to contact the two end faces of the guide wheels 31. The bottom of the support base 1 has slots 11 for inserting into the limiting plates 55. One end of the slide 53 faces the pipe bending device 6, and the end of the slide 53 facing the pipe bending device 6 has a limiting component 57, which is used to contact the side of the support base 1 to limit the sliding position of the support base 1.

[0053] It should be noted that the support base 1 slides on the slide rail 53 via the traveling mechanism 3. When the support base 1 contacts the limiting component 57, the support base 1 slides into place. The two limiting plates 55 contact the two end faces of the guide wheel 31 respectively, which can laterally limit the guide wheel 31, and thus laterally limit the support base 1.

[0054] In some embodiments, such as Figures 1 to 10As shown, the walking mechanism 3 includes four mounting seats 32, four lateral sliding structures 33, and four limiting structures 34. The four mounting seats 32 are respectively located at the four corners of the support base 1. Each mounting seat 32 is rotatably equipped with a guide wheel 31. The four lateral sliding structures 33 are respectively connected to the corresponding mounting seats 32. The four corners of the support base 1 are provided with lateral sliding grooves 12, and the lateral sliding structures 33 are slidably disposed in the lateral sliding grooves 12. The four limiting structures 34 correspond one-to-one with the lateral sliding structures 33 and are respectively disposed on the corresponding lateral sliding structures 33. The lateral sliding structure 33 has a first sliding position and a second sliding position. The lateral sliding grooves 12 are provided with first limiting grooves 13 at the first sliding position and the second sliding position. The limiting structures 34 are used to insert and cooperate with the first limiting grooves 13.

[0055] For example, the mounting base 32, the lateral sliding structure 33, and the limiting structure 34 are divided into four groups. In this embodiment, one group of mounting base 32, lateral sliding structure 33, and limiting structure 34 is used as an example for explanation. The lateral sliding structure 33 is fixed on the mounting base 32. By sliding the lateral sliding structure 33 in the lateral sliding groove 12, the mounting base 32 and the guide wheel 31 can be driven to slide laterally. The limiting structure 34 slides and engages with the lateral sliding structure 33, and the limiting structure 34 can be inserted and engaged with the first limiting groove 13. After the lateral sliding structure 33 slides into place, the limiting structure 34 is inserted and engaged with the first limiting groove 13. At this time, another part of the limiting structure 34 is connected to the lateral sliding structure 33, thus enabling lateral limiting of the lateral sliding structure 33.

[0056] In some embodiments, such as Figures 1 to 10 As shown, the transverse slide 12 includes a first slide 121 that passes through the support base 1, and a second slide 122 that is disposed on the top of the support base 1 and communicates with the first slide 121; the first slide 121 and the second slide 122 have the same length, and the width of the second slide 122 is greater than the width of the first slide 121; the transverse sliding structure 33 includes a first sliding part 331 that slides with the first slide 121, and a second sliding part 332 that slides with the second slide 122; the two opposite sides of the second sliding part 332 respectively contact the two side walls of the second slide 122.

[0057] It should be noted that the longitudinal section of the first slide groove 121 and the second slide groove 122 is T-shaped, and the longitudinal section of the first sliding part 331 and the second sliding part 332 is T-shaped; the mounting base 32 spans the first slide groove 121, so the cooperation of the mounting base 32 and the second sliding part 332 can play the role of height limiting.

[0058] In some embodiments, such as Figures 1 to 10As shown, the lateral sliding structure 33 has a second limiting groove 333, which is used to align with the first limiting groove 13. The limiting structure 34 includes a limiting slider 341, an elastic element 342, and a driving component. The limiting slider 341 is slidably disposed within the second limiting groove 333. One end of the limiting slider 341 is used to engage with the first limiting groove 13 to laterally limit the lateral sliding structure 33. The elastic element 342 is disposed within the second limiting groove 333. Both ends of the elastic element 342 are respectively connected to the bottom walls of the limiting slider 341 and the second limiting groove 333. The driving component is disposed on the lateral sliding structure 33 and is used to pull the limiting slider 341 back into the second limiting groove 333 to separate the limiting slider 341 from the first limiting groove 13. The elastic element 342 includes a spring.

[0059] It should be noted that after the lateral sliding structure 33 slides into place, the limiting slider 341 extends under the elastic force of the elastic element 342. At this time, the outer end of the limiting slider 341 is engaged with the first limiting groove 13, and the other end of the limiting slider 341 is located in the second limiting groove 333. Therefore, the lateral sliding structure 33 can be laterally limited. When it is necessary to adjust the position of the lateral sliding structure 33, the limiting slider 341 can be separated from the first limiting groove 13 by pulling the driving component, and the position can be adjusted laterally. After the adjustment is in place, the limiting slider 341 can re-engage with the first limiting groove 13 under the elastic force of the elastic element 342, thus limiting the adjusted lateral sliding structure 33.

[0060] In some embodiments, such as Figures 1 to 10 As shown, the transverse sliding structure 33 has a rotating groove 334 inside, and the driving component includes a pull rope 343 and a rotating shaft 344; one end of the pull rope 343 is connected to the limiting slider 341, and the other end extends into the rotating groove 334; the rotating shaft 344 is rotatably disposed in the rotating groove 334; the position of the rotating shaft 344 relative to the transverse sliding structure 33 is fixed; the other end of the pull rope 343 is fixed on the rotating shaft 344; wherein, the top end of the rotating shaft 344 extends out of the transverse sliding structure 33.

[0061] For example, a rotating part 345 is fixedly provided at the extended end of the rotating shaft 344. By providing the rotating part 345 on the rotating shaft 344, it is convenient for the operator to rotate the rotating shaft 344. After rotating the rotating shaft 344, the pull rope 343 can be wound around the rotating shaft 344, thereby providing a pulling force to the limiting slider 341, sliding the limiting slider 341 into the second limiting groove 333, and separating the limiting slider 341 from the first limiting groove 13. At this time, it is convenient for the operator to adjust the position laterally.

[0062] In some embodiments, such as Figures 1 to 10As shown, a clearance groove 56 is provided on the ground 5, and a second groove 52 is provided at the bottom of the clearance groove 56; the lifting mechanism 4 includes a lifting plate 41 and a hydraulic cylinder 42; the lifting plate 41 is disposed in the clearance groove 56; the hydraulic cylinder 42 is disposed in the second groove 52; the cylinder body of the hydraulic cylinder 42 is fixed in the second groove 52, and the piston rod of the hydraulic cylinder 42 is connected to the bottom of the lifting plate 41. The bottom of the support base 1 has an anti-rotation groove 14 that is inserted and engaged with the lifting plate 41.

[0063] It should be noted that by engaging the lifting plate 41 with the anti-rotation groove 14, the position of the support seat 1 can be circumferentially limited, reducing the possibility of rotation of the support seat 1. There are two hydraulic cylinders 42 and two second grooves 52, with the two hydraulic cylinders 42 respectively disposed in the two second grooves 52. Through the above-mentioned configuration, the stability during the lifting process can be improved. When the hydraulic cylinder 42 pushes downward into place, the lifting plate 41 is located in the clearance groove 56 and the lifting plate 41 is separated from the support seat 1. Through the above configuration, when the bent pipe falls onto the support seat 1, the impact force transmitted to the lifting plate 41 can be reduced.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
